More efficient Atom feeds for public-inbox

More efficient Atom feeds for public-inbox

[Leah Neukirchen]

Hi,

currently, public-inbox sends the Atom feed with
Content-Type: application/atom+xml and no further headers.

Since many feed readers poll feeds quite often, this creates noticable
traffic and load.

Would it make sense to serve the <updated>...</updated> field as
Last-Modified and/or compute some ETag, so feed readers can use
conditional GET?

thx,

Yes, thanks for the reminder.  I think some updates to the
streaming code needs to be made.

Btw, would you happen to know if ETag or Last-Modified support
is more common amongst common feed reader clients?

(btw, I thought I replied to this email many hours ago, but
 I don't think it went out before I lost power :x)

I don't know, but I guess most serious software supports both, so just
having ETag should be fine too.
